Our own 0–100 rating, built from five aspects: art, character, story, the sensory experience and how well a film rewatches.

  • Art & Craft 92

    Artistic execution stands out as a primary strength of the film. Reviewers consistently commend the cinematography, vivid color palette, and meticulous production design that capture northern Vietnam’s landscapes. Direction is described as confident, and visual effects are praised for their quality, though a few note moments of sterility in the overall production.

  • Character & Emotion 78

    Characterization receives mixed evaluations across the reviews. Many viewers applaud nuanced performances, especially the chemistry between Detective Kiên and Miss Moon, describing it as engaging and complementary.

Despite these criticisms, the majority perceive the core cast as competent, contributing positively to emotional impact.

  • Story & Flow 70

    The narrative blends detective and horror motifs with a series of twists. Positive remarks emphasize a logical, tightly scripted plot that maintains suspense and delivers satisfying revelations. However, some feedback cites predictable beats, an early twist that reduces tension, and a protracted conclusion. Balancing these perspectives, the story is generally regarded as solid but occasionally uneven in pacing.

    Sensory components, including soundtrack and sound design, are highlighted as immersive and well‑matched to the film’s tone. Viewers praise the haunting music, clear audio mix, and striking visual style that enhances atmospheric tension.
